not sure if I'm doing this right

Answer 1

Yes you have done perfectly correct.

The concept goes like.

Find the volume of the pile to be buyers = 5x7x12 = 420 cubic feet

Now divide this volume by 128 to find number of piles costing 100 each.

And than multiply this number which is 420/128 by 100 to get total cost
